View or change collection set schedules (SQL Server Management Studio)
Applies to: 
SQL Server
You can view or change collection set schedules by using SQL Server Management Studio.
The collection mode, cached or non-cached, determines how you can make changes to a schedule. Cached mode uses separate schedules for collection and upload. Non-cached mode uses the same schedule for collection and upload. The type of collection mode for each of the system data collection sets is as follows:
- Disk Usage uses non-cached collection mode
- Query Statistics uses cached collection mode
- Server Activity uses cached collection mode
View collection set schedules
In Object Explorer, expand the Management node, expand Data Collection, and then expand System Data Collection Sets.
Right-click a collection set name, and then select Properties to open the Data Collection Set Properties dialog box.

You can change the collection frequency on the General page. To do this, follow these steps:
In the details pane, double-click the number that is displayed for the Collection Frequency (sec) column in the Collection items table.
To increase or decrease the collection frequency, type a lower or higher number, and then press ENTER to store the new value.
To change the existing upload schedule for the collection set, follow these steps:
Select the Uploads page.
In the details pane, select Pick.
The Pick Schedule for Job dialog box opens. The available schedules appear as a table.
